EXPERIENCE

QUALCOMM Inc. San Diego, California
Senior Staff Engineer October 2002 to November 2005
Staff Engineer October 1997 to October 2002
Senior Engineer October 1996 to October 1997
Engineer August 1995 to October 1996

Most recently served as a senior system architect for Qualcomm Wireless Business Solutions (QWBS) OmniVision satellite mobile communications system. Implemented significant portions of the network management segment including the forward scheduler, which maintains forward message state for the entire system. Senior system architect and implementor of network server software for Qualcomm's OmniExpress product, which used a proprietary sliding-window UDP-based protocol over SprintPCS CDMA wireless data network. Later became mobile terminal and integration lead for the project. (C under VMS)

Project engineer and system architect for a patented driver verification system (6,108,591: Method and apparatus for validating vehicle operators). Patents for two other inventions are currently pending with the USPTO.

Designed and implemented image and audio software for the Qualcomm Digital Cinema encoder, part of a secure digital in-theatre motion picture distribution system. My portion of the project dealt with encoder output file management and quasi-realtime hardware control using SNMP. Also wrote test code to debug audio synchronization issues. (C under Linux and IRIX)

Developed embedded software for the OmniTRACS satellite mobile communications terminal, eventually becoming the mobile terminal software lead. (C and 80C186 assembly under proprietary RTOS)

In 1997 was named by my peers "Engineer of the Year" for the OmniTRACS division.

Gulbransen (now Midi 9) San Diego, California
Consultant August 1995 to August 1998 (on an as-needed basis)
Embedded Systems Software Engineer October 1990 to August 1995

My primary responsibilities centered around the development of several digital pianos and acoustic piano MIDI retrofit products using Intel 80C186 embedded processors. Most of the code modules were written in C, with a few modules in assembly and C++. During the last few years at Gulbransen I was "the Korean piano guy," having sole responsibility for developing and maintaining the embedded software used in Gulbransen's OEM digital piano products which were manufactured and marketed by three different Korean manufacturers. This business accounted for the majority of Gulbransen's revenue. Specific tasks include:
  • Designing, writing, testing, and maintaining code for a variety of MIDI, floppy disk drive, LCD, control panel, and other hardware configurations under multiple product baselines
  • Performing run-time code efficiency studies using HP 1660A logic analyzer running System Performance Analysis (SPA) and using this information to improve algorithm efficiency
  • Debugging prototype hardware using oscilloscopes and HP logic analyzers
  • Developing a keyboard scanner using Motorola 68HC05 microcontroller
  • Performing on-site technical support for Gulbransen endorsees including Chick Corea, Bruce Hornsby/Grateful Dead, Van Cliburn, and Marc Shaiman
  • Providing ongoing software support to OEM customers, including travel to customer facilities in Seoul, South Korea
  • Writing user and installation manuals
